VALVE.

APPLICATION FILED OCT. l2. l9|2A Patented Aug. 31, i915.

To all al1/mm 'it may conc-cm f Be it lrnoivn that l, WILLIAM Brisanz, a citizen of the llnited States, and a resident of Chicago, in the county of Cool; and State of lllinois, have invented certain new and useful lmproveinents in Valves; and l do hereby declare that the following is a full, clear, and enact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciication.

This invention relates to an improvement in valves containing a plurality of partsv which have to be set or placed in a certain predetermined combination relation in order to open the valve.

My invention is adapted to be applied to a valve structure placed in a pipe-line conducting a fluid from a source of supply to control the flow therefrom and may be applied to a pipe-line from a gasolene supply tank to controlthe flow of gasolene to the carbureter of an automobile.

The advantage of my improvement Will appear as I proceed with my specication.

ln the drawings, Figure 1 is a view representing a side elevation of a valve mechanism embodying my invention. Fig. 2 is a view representing a longitudinal central section through the same. Fig. 3 is a view representing a front end elevation of the valve structure. Fig. 4 is a view representing a transverse section taken in a plane indicated by the line 4-fl of Fig. Q. Fig. 5 is a View similar to Fig. 4 ivith the parts in a different relation. Fig. 6 1s a View sirmlar to Fig. 5 illustrating a modified lorm ot myl invention.

Referring now to that embodiment of my invention illustrated in the drawings, 10 indicates a tubular valve casing Within which are nested aplurality of tubular valve plugs 11. Said valve plugs are :capable 'of rotation with reference to each other and With reference to the valve casing. The valve casing 10 is open at one end and is closed at its other end by a Wall 10a. Said casing is provided intermediate its ends with laterally opening inlet and outlet ports extending, as shown, respectively, through bosses 10', 10C, which threaded for connection with the pipe line in which the valve structure is placed. rlhe valve plugs 11 also each o' have end Walls 11a.

To the open end ot the tubular valve casepeclcation of Letters Patent.

application lcfl ctober 12, 1912. Serial No. 725,360.

ing is attached a aed dislr the upper face of which is stepped to provide a plurality of vertically spaced circular faces 12a, 12b, 12C, one for each et the valve plugs. Said faces are graduated in a circumferential direction, each face being divided into a like number ott equal angular graduations, which are indicated by nunerals 12X, 12F, 12% The said graduations, as shown, are indicated by notches 13 in the peripheral edges of the several faces and the numerals indicating the several graduations are numbered consecutively in a circular' direction, there being, as shown, twelve of said notches in each face. Preferably the like numerals of the several faces are not placed in radial alinement, the zero point of one dial face being angularly separated from the zero point of either of the other dial faces, for a purpose presently to be described.

The open end of each valve plug is closed by a disk 15, 16, 17, respectively, and said disks are made integral or rigid With devices which project beyond the valve structure in such manner that the several valve plugs may be independently rotated Within the valve casing by means operable from the outside of the valve structure. As shown, the valve dislr 15 of the inner valve plug is made rigid with a longitudinally extending centrally disposed rod or stem 15a, While the valve disks 16 and 17 are made integral With concentric tubular stems or sleeves 16a and 17a, respectively, which have rotative bearing the'one Within the other and upon said rod or stem 15a and also Within a sleeve 12e made rigid with the disk 12 of the valve casing.

To each or' the stems of the valve plugs is secured, respectively, a radial arm 19, 20, 21, carrying at its outer end a detent 19a, 20a, 21a, adapted for engagement in one of the graduation notches of one of the dial faces on the disk 12. As shown, each ot' said arms is threaded upon its valve stem, and thumb nuts 22, 23, 24, respectively, are like- Wise threaded upon said valve stems and act as jam nuts to lock said arms in any predetermined angular position on their respective valve stems.

ll ch valve plug is provided with inlet and outlet ports 26, adapted to be brought simultaneously into alinement with the inlet and outlet ports of the valve casing.

t is apparent that by rotating the valve plugs by means or the arms 19, 2G and 21,

the inlet and outlet ports of each valve plug may be simultaneously brought into alinement with the inlet and outlet ports of the casing, as shown in Figs. 2 and 4, in which case a free passage will be aiforded through the valve structure. In this position of the valve plugs the several detents on the actuating arms of the valveestems will correspond in position with certain graduations on their respective dial vfaces andl thus, in order to open the valve, it is essential that 'the one'operating it shall know these par' ticular graduations. In other words, he

-must know the combination of the valve structure\in order to'operate it, as in all of the positions of the.valve operating arms,

. except those predetermined positions known Yseveral inlet and outlet structure in the casing will not be in alineonly to the one having the combination, the ports of the valve ment and the valve will be closed.

As will be apparentfvit is possible to change the combination should it become known to others than those authorized to know it by simply setting the valve .on its old combina-tion and then, loosening oneor more l of the jam nuts on the several valve stems,

ports of restricted may be-partially closed olf and yet permit running.

sufficient gas to enter the engine to keep it In Fig. 6 I have shown the va-lve plugs provided with restrictedinlet and outlet -ports 27, 28, respectively,

. brought into alinement by means of a diHer- .ent combination than that of the main inlet4 and outlet ports. Thus, when one leaves the automobile he may set the operating arms of the valve in a position corresponding to the position of the inlet and outlet small valve ports 27, 28, when sulicient gas. will be supplied the engine to prevent it from stopping but will not be sufficient -to start the engine under load.

The advantage of my improved valve structure will be apparent to those familiar with the art. It is simple in construction and economical to manufacture and assemble.

Vhile in describing my improved valve I have shown but three 'valve plugs, it is apparent that the structure may be made more complicated and less likely to be tampered which may be with by adding to the number ot valve'A plugs,thus increasing the difficulty of orming the combination to open the valve.

I claim as my invention 1. A. valve structure comprising a tubular casing having anintegral bottom'wall andalined inlet and outlet ports, an apertured dial member formingthe top 'wall' of said casing, said dial member having setsy of graduations, a plurality of concentric tubular valve plugs each having an integral bottom wall, rotatively mounted and nested in said casing and in each other, each'valve plug being provided lwith inlet and outlet ports adapted to be brought into alinement with the inlet and outlet port of said valve casing, a valve stenrxed to and closing the vtop of each valve plug, said stems being nested within each other and arranged to eX- tend through the aperture in said dial, means fixed to eachvalve stem for rotating its .associated valve member independently of the `other vulve members, and an indicator movable with each tubular valve plug adapted to register with an associated set of graduations on said dial.`

2. A valve structure comprlsing a tubular casing having an integral bottom wall and alined inlet'and outlet ports, an apertured dial member forming the top Wall of said casing, said dial member having sets of graduations, a plurality of concentric tubular valve plugs each having anintegral bottom wall, rotatively mounted andv nested in said. valve casing and in each other, each valve plug being provided with inlet and outlet ports adapted to be brought into alinement with the inlet and outlet ports of said valve casing, concentric nested valve stems o ne for each valve plug having rotative bearing within the aperture in said dial and projecting beyond the same, the inner valve plug stem projecting successively beyond the valve stem oi' the adjacent valve plug, arms fixed to said valve stem, indicators fixed to said arms and adapted to register with an associated set of graduations on said dial and means for attaching said armsnto said valve plugs providing angular adjustment of said indicatorsv with reference to said.

valve plugs.

In testimony, that I claim the foregoing as my invention I affix my signature in the presence of two witnesses, this 9th day of October A. D. 1912.
